To (ill whom it may concern Be it known that I, JULIUS J. MILLER, a citizen of the United States of America, and resident of St. Joseph, Berrien county, Michigan, have invented a certain new and useful Improvement in Stapling-lvIachines, of

' which the following is a specification.

-My invention relates to stapling machines of the type employed for fastening the heads or ends of wirebound boxes to cleats on the box sides. and which operate within the box for inserting the staples outwardly.

Among other objects, my invention is intended to provide an inside box stapler adapted for operating close to the inner sides and in the corners of the box and for forming its own staples near and directed to ward the point of their application.

The invention further contemplates an ar rangement whereby a. standard, ordinary or other suitable staple former and drivermay be cniployed for making the staples within the box; also the provision of a stapler adapted to reach within, support and gage the work and to formand drive the staples upwardly.

The nature of theinvention will be bestunderstood from the following description with reference to one form of machine containing an embodiment of my invention which is shown for illustration in the accompanying drawings.

In the said drawings:

Figure l is a side elevation of the illustrative machine, showing the frame thereof in vertical section.

Fig. 2 is a plan view of the said machine.

Fig. 8 is a vertical section on line 33 of Fig. l.

Fig. 4 is an enlarged detail view of the staple driver with adjacent parts shown in section.

outer end portions of the rest of support Fig. 5 is a perspective view of a \virebound upon which the boxes are manipulated While the staples are being driven.

F i'g. 9 is a,top plan of the mechanism shown in Fig. 6 by which the staple is formed and inserted in the said carrier. Fig. 10 is a, section on line 10-10 in Fig. 6.

Fig. 11 is a perspective view of the carrier by-which the staples are transferred to the position where they are driven in the box by the secondary driver.

Fig.12 is an enlarged detail section on line 12-12- in Fig. 3

Fig. 13 is a perspective of the staple former.

Fig. 14 is a perspective of what may be termed the primary staple driver -or ector that is to say, theelements associatedwith the former and which corresponds to an ordi nary staple driver, but which in this case does not insert the staple directly into the box, being-used merely for ejecting the staple and drivinq the same into the carrier and guide shown in Fig. 11.

The illustrative machine comprlses aframe A having a horizontal arm B and a staple forming and driving mechanism carried thereby arranged for operation .within the box. provided with devices for forming the staple with its points up and fordriving the same upwardly at the terminal portion or nose of said arm; said terminal portion or nose which is formed by the converging plates/i being adapted to reach into the box corners and to be engaged by the sides of the ranged inside the cleats (5 and stapled there-' to. The stapling of the heads to the cleats is preferably done by driving the staples from the interior of the box through the heads or end boards 4 and into the cleats, whereby the staples pass throu h the thin wood lirst and then enter the thicker pieces of" wood constituting the cleats.

In performing such operation on the illustrative machine, the end board rests iipon the arm B, as seen in Fig. 6, and the opera.- tor manipulates the box on arm While perating the machine successively to drive a row of staples through each clcat,thaz to say, through the head or end board along lines which cause the staples to pass into the cleats; and in this operation the tapered nose or terminal of the arm B serves as a guide for enabling the operator to posi- Lion the Work and to gage the staples from the box sides.

Referring to if l, the stapling nnzchanisn'i as a Whoie nprises a forming inc,

nism G with s iated Wire-feeding and cutting dev ces ,Wli' .h mechanism maybe a conventionai staple former and driver),

a staple guide and carrier Q, and a final driver I operas vertically at substantially the temiinal oi the arm E. To permit feed ing and cutting a sxnhicio length of staple wire to form the require 1 While at the same time closely associating the forming and driving devices to bring the entire operation substantially at the terminal of said arm, the staple forming and as sociated devices are arranged at an angie behind the driver I, so that the forming and driving lines converge toward the point of application of the staple, and the staple is formed pointing toward the work and is shifted only slightly to position tube driven. The Wire feeding, cutting, staple forming, guiding and driving devices operate in substantially the same plane so as to avoid in terference with the manipulation of the bon on the supporting arm B, and with this arrangement of the mechanism the staples are presented and driven crosswise of the box cleats.

The staple carrier and guide C consists of a tapered block provided with a vertical staple guide passage in its forward end, said block being pivoted to swing from the oblique position shown in Figs. 1 and i to a vertical position in which it fits between the converging plates 6, in the latter position the guide passage 0 being directly over the staple driver I. The back of the block C has pivot bearings c at its top, and lower down pivot bearings c for connecting it with the operating rod D, which latter rocks the said block about its axis to move it back and forth from one position to another. .A retracting spring (Z is applied to the rod D and the rear end of the latter is provided with a roll or Wheel (Z adapted to engage a cam E on the drive shaft F. Said rod'D is mounted to slide endwise in bearings on the frame, and the outer end of the rod preferably has a pin and slot connection with the block C, so that sufficient lost motion is provided to enable the horizontal reciprocation of the rod to swing the block length oi staple, i

about its axis. The said'cam'lfi is adapted to push the rod i'orviard'and bring the block C upwardly to vertical position, so that the staple can be til'l The spring (2 then retrac the rod D at the proper time, causing the said staple carrier and guide C to move back lo a position for receiving another stag;

Sta, les are successively formed and introduced into the carrier bloclt C by the angularly arranged mechanism {1%, which may be oi? any 5 Jlfilllle linoivn or approved oharac A, hovvn, it comprises a lmown staple forming and driving incchacomprising" a staple former g, staple nd loop bar anvil which are erated inany known or suitable manner.

rigidly attached to an actuating head 1" which also carries the pawl or feed finger g for the staple Wire feed mechanism, and

which head is operated by an arm 9 pivoted at g on the frame. vAs the mechanism is invert-ed, however, the spring 9 is applied for holding the staple former in operative position until after the driver g has driven the-staple into the guide 0 of the block C. The operating arm 9 preferably has a lost motion connection with the head in view of the fact that the driver and former must reciprocate in a strai ht line, Whereas the movement of the arm g is about an axis. The said arm g has its rear or shorter end portion provided with a roll or Wheel 9 adapted to engage the cam H upon the shaft F, whereby the rotation of the shaft causes the arm g to operate the said'niechanisin.

Referring further to the details of said mechanism G, the dog is pivoted on the driver 5] and engages the end of the former 9', being held in this position by the spring G thereof, iihcn the cam'g on said dog 31 strikes the cam after the stape is formed, the dog is then. disengaged from the "former y, permitting the driver (7 to continue alone. lVhen the portion g of the driver 9 engages the staple the latter is driven forward into the guide 0 of block C. This is possible, of course, by reason of the fact that the portion oi the loop bar moves into the groove 9 on the driver thus allowing the loop bar to swing on its pivot and move out of the path of the portion 9 of the driver.

The driver 9 of the mechanism above described may conveniently be termed the pri' mary driver as distinguished from the one which drives the staple from the guide block G into the work, the latter driver being herein referred to as the secondary driver.

5/ on the stationary heath 3 The loop bar 9 is pivoted at G T here is The said secondary driver I is provided and arranged to slide vertically in bearings ion the forward terminal of the frame. This driver is made thin and of a shape. to enter the guide passage 0, when the block t is in its operative or vertical position, and thus the staple is driven upward by the said secondary driver. This driver I is operated by an arm a" fulcrumedat g. It will also'be seen that the rear end of this arm is provided with a roll or wheel 2' adapted to engage a cam J on the said drive shaft. Springs'K and L are provided for holding the rear ends of the arms {Wand iin engagement with their respective cams.

'A clamping arm or foot M is arranged above the arm or table B, and is fulcrulned at m, whereby its forward end mt may be brought downward to bear upon the head or end board of the box, thereby resisting the upward thrust of the staple driver I during the operation of driving the staples.

The rear end of this arm M is providedwith a roll or wheel m adapted to engage a cam N. on the drive shaft. A retracting spring n serves to keep the rear end of the arm Min engagement with its allotted operating cam on the shaft.

As before stated, the box head rests upon the arm B during the stapling operation, and the tapered terminal or nose of the arm serves by engagement with the successive box sides for positioningthe Work and gaging the position of the staples. One side of the box slides along against one of plates 6 until the staples at that side are driven, and then the bottom of the box slides straight across the flat outer face 0 of the block 0 while another row of staples are driven. and then the other side of the box slides outwardly upon the other plate 6 during the driving of the last row of staples. The foot-0r clamping arm M rises and releases the box after the driving of each stapleemzbling theoperator to move the box the required distance for driving the next staple. The staples are made by the mechanism G, and

. are transferred from this mechanism by the .block C to the position for driving. and the driving is accomplished by the secondary driver I in the manner explained.

With the illustrative.construction, the

staple is formed and driven pointed toward the work, beingfoirmed substantially hear the thedriving point; in fact the staple is formed and thrust forward from the forming mechanism G to a position with its points near- .st' the place of insertion, so that the. re-

maining movement for insertion of the staple into the work is compa'atively slight. While there is some lateral shift in movement of the staple from forming to driving position, this is accomplished by an endwise movement of the staple toward the work; and thus in a sense the function of relative to the driver I, operating vertically beneath the forward end of the tapered nose of the arm B, the forming mechanism may be of any necessary or desired width, according to the length of staple wire required to provide a staple of the desired length, while at the same time the entire mechanism is snugly arranged and closely associated at the driving point, without interfering with the desirable capacity of the machine to drive the staples into the cleats close to the box sides and in the corners thereof.

Obviously the present invention is not limited to any particular structural details or mode of operation, which may be variously modified; nor is it indispensable that all the features of the invention be used conjointly since they may be used to advantage in various different combinations and slib-combinations.
